A Portable Visual Assistant System for Driving Crawler Construction Machinery up and down Flat Transport Vehicle

The crawler construction machinery has great destructive power to the road surface, and needs to be loaded by a flat transport vehicle on the asphalt or cement road. Usually, the driver cannot observe the relative position of the machinery crawler belt and the vehicle crawling ladder under the machinery body. It brings difficulties for driver driving crawler construction machinery up and down the flat transport vehicle. To solve this problem, a portable vision assistance system is designed based on wireless network, which assists drivers to observe the blind spot area. The system consists of image acquisition and transmission module, optional wireless routing module, and image reception and display module. An electromagnet is utilized for the adsorption of the image acquisition and transmission module on the machinery body for the convenience of installation and removal. The optional wireless routing module is utilized for multiple cameras, and the image reception and display module is set in the driving room for the driver to observe the blind spot. Experiment results verify the effectiveness of the system, and it can be used under high-intensity vibration of construction machinery.
